Description
High-Precision C32-ER25 x 100L Cylindrical Shank Baby Collet Chuck Holder (Slotted Nut)
The MTM C32-ER25-100L cylindrical shank baby collet chuck holder delivers maximum rigidity and vibration dampening for heavy CNC milling and production tooling. Its heavy-duty straight shank (Ø32mm) and ER25 slotted nut ensure exceptional stability with runout accuracy ≤ 0.005mm.
Key Features & Benefits
- Heavy-Duty Straight Shank: 32mm cylindrical shank resists strong cutting forces and deflection during heavy roughing cuts.
- Wide Clamping Range: Clamps tooling shanks from 1.0mm up to 16.0mm diameter using standard ER25 collets.
- High-Speed Dynamic Balancing: Pre-balanced up to 15,000 RPM for vibration suppression and extended cutter life.
- Sub-Micron Grinding Accuracy: Precision ground shank and taper with runout accuracy ≤ 0.005mm.
